Wind Turbine Blades (WTBs) are a key structural component of the Wind Turbine (WT) and are crucial to efficient energy generation. The consequences of blade failure can be catastrophic and therefore a means of continuously monitoring the blades to determine their condition will provide significant benefits.
In this research, physics based Structural Health Monitoring (SHM) techniques will be developed to assess the damage severity of in-service WTBs. Experimental responses from a small scale WTB from a 5kW WT will be obtained then subsequently used to update a Finite Element Model (FEM). Uncertainties will be quantified using soft computing techniques namely application of fuzzy logic to Finite Element Model Updating (FEMU). This process provides a more accurate representation of the healthy structure, ensuring the analytical model closely represents the experimentally observed response.
To evaluate the proposed damage severity estimation method, damage will be introduced both experimentally and numerically. Investigation into the common damage mechanisms and locations will be presented to ensure realistic scenarios are represented. Non-destructive damage will be simulated experimentally through addition of small masses inducing a structural modification similar to damage. For comparison purposes, damage will be simulated numerically via addition of mass elements to the FEM.
